    LVI project

    user_301665782

      Hi everyone and again I hope some of you can help me with that:

         

      I am trying to save some variables  when  Vdda  and /or Vddd  drop down 2.95 V.

         

      I have tried to adapt  the example  "D"  on  AN 54460  for Low voltage interrupt.

         

      I have created a small project to test the LVI feature.

         

      To verify that the ISR is working  I have set the variable "Led_On" inside the ISR.

         

      Later in the main loop,  when Vddd  or Vdda drop below  the threshold,  I should see  the  led connected to  the Pin 1(2)  turn on a some fraction of second .

         

      That  not happen,  I do not know  what is missing.

         

       

         

      Thank you very much for any help.
